    摘要： The present invention enables the desired area on a luminal organ to be held correctly during laparotomy or laparoscopic surgery, even without carrying out dot inking which requires a high degree of skill. In the present invention, a magnetic body is pre-anchored at a specific position inside a luminal organ. During surgery, a magnet is brought close to the outside of the luminal organ, such that the magnetic body is adsorbed to the magnet, along with the body tissue of the luminal organ, enabling traction.

    摘要： Intraoperative tissue treatment methods are used following the removal of target tissue, e.g. diseased tissue, from a target site, e.g. within a patient's breast, leaving access to the target site. In one method an expandable element is introduced into and expanded within a void at the target site. If it is determined that all of the target tissue was not removed, then a layer of tissue at least partially surrounding the expanded element is removed from the patient, preferably in a substantially intact form, to permit inspection for evidence of the target tissue still within the patient. In a second method the suction inlet of a suction device is located so to be in fluid communication with the void. Fluid is then withdrawn through the suction inlet so to at least partially collapse the tissue defining the void. If it is determined that all of the target tissue has not been removed, at least a portion of the collapsed tissue is removed from the patient and analyzed for evidence of target tissue still within the patient. With a third method, the sheath is maintained along the passageway from the region external of the patient to the void at the target site. A flexible implant is passed through the sheath and into the void so to at least substantially fill the void. The sheath is then removed from the patient.

    摘要： Ultrasound applicators able to both image a treatment site and administer ultrasound therapy include an array of transducer elements that can be focused. In several embodiments, an electronically phased array is used for controlling the focal point of an ultrasound beam. The ultrasound beam produced thereby can also be electronically steered. To reduce the quality factor or Q of the array when the array is used for imaging, an electronic switch is selectively closed, placing a resistance in parallel with each of the array elements. A flexible array is employed in several embodiments and is selectively bent or flexed to vary its radius of curvature and thus control the focal point and/or a direction of focus of the array. In another embodiment, each of the transducer elements comprising the array are individually mechanically pivotable to steer the ultrasonic beam produced by the transducer elements.
